The group of 34 athletes and organisers travelled there for the games.
The hosts treated the athletes to a traditional American pig roast and pot luck dinner followed by a game of Australian Rules Football.
City of Casey mayor Janet Halsall said the group had the trip of a lifetime.
“They’ve been competing in the sports they love, living with American host families, and sharing in celebrations for Sister Cities Day and American Independence Day.”
She said the sister city relationships were an important forum for cultural, economic, and educational exchange.
The City of Casey’s Sister City link with Springfield Ohio was established by the former City of Berwick in 1985.
